It seems a Pulitzer Prize winning columnist and blogger is so stupid in the ways of technology that he didn't realize posting comments in a false name on a competitor's blog could be found out. It seems the other blogger looked at the IP address and tracked the derogatory posts to the columnists (are you listening, Milton?) Now the columnist is in trouble.
